|Extinct||by 900 AD|
There is virtually no direct attestation of Pictish, short of a limited number of place names and names of people found on monuments and the contemporary records in the area controlled by the Kingdom of the Picts.
The term "Pictish" was used by Jackson (1955), and followed by Forsyth (1997), to mean the language spoken mainly north of the Forth-Clyde line in the Early Middle Ages. They use the term "Pritennic" to refer to the proto-Pictish language spoken in this area during the Iron Age.
Language classification 
The existence of a distinct Pictish language during the Early Middle Ages is attested clearly in Bede's early 8th-century Historia ecclesiastica gentis Anglorum, which names Pictish as a language distinct from that spoken by the Britons, the Irish, and the English. Bede states that Columba, a Gael, used an interpreter during his missionary work in Pictland. A number of competing theories have been advanced regarding the nature of the Pictish language:
- Pictish was an Insular Celtic language allied to the P-Celtic (Brythonic) languages (Welsh, Cornish, Cumbric, Breton, Brittonic)
- Pictish was a Insular Celtic language allied to the Q-Celtic (Goidelic) languages (Irish Gaelic, Scottish Gaelic and Manx)
- Pictish was a Germanic language allied to Old English, the predecessor to the Scots language
- Pictish was a Pre-Indo-European language, a relic of the Bronze Age
The current academic consensus is that Pictish was a P-Celtic language that came under increasing pressure and influence by the Gaelic language of Dál Riata from the fifth century until its eventual replacement.
Position within Celtic 
The evidence of place names and personal names demonstrates that an Insular Celtic language related to the more southerly Brythonic languages was formerly spoken in the Pictish area. The view of Pictish as a P-Celtic language was first proposed in 1582 by George Buchanan, who aligned the language with Gaulish. A compatible view was advanced by antiquarian George Chalmers in the early 19th century. Chalmers considered that Pictish and British were one and the same, basing his argument on P-Celtic orthography in the Pictish king lists and in place names predominant in historically Pictish areas.
Celtic scholar Whitley Stokes in a philological study of the Irish annals concluded that Pictish was closely related to Welsh. This conclusion was supported by philologist Alexander MacBain's analysis of the place and tribe names on Ptolemy's 2nd century Geographia. Toponymist William Watson's exhaustive review of Scottish place names demonstrated convincingly the existence of a dominant P-Celtic language in historically Pictish areas, concluding that the Pictish language was a Northern extension of British and that Gaelic was a later introduction from Ireland.
William Forbes Skene argued in 1837 that Pictish was a Goidelic language, the ancestor of modern Gaelic. He suggested that Columba's use of an interpreter reflected his preaching to the Picts in Latin, rather than any difference between the Irish and Pictish languages. This view, involving independent settlement of Ireland and Scotland by Goedelic people, obviated an Irish influence in the development of Gaelic Scotland and enjoyed wide popular acceptance in 19th-century Scotland, but is no longer given credence.
While Skene's notion of an exclusively Q-Celtic Pictish language has long been rejected, the Picts were under increasing political, social and linguistic pressure from Dál Riata from around the fifth century. The Picts were steadily Gaelicised through the latter centuries of the Pictish Kingdom, and by the time of the merging of the Pictish and Dál Riatan kingdoms, the Picts were a Gaelic-speaking people. Forsyth (1995a) speculates that a period of bilingualism may have outlasted the Pictish kingdom in peripheral areas by several generations.
Germanic theory 
Traditional accounts (now rejected) claimed that the Picts had migrated to Scotland from Scythia, a region that encompassed Eastern Europe and Central Asia. Buchanan, looking for a Scythian P-Celtic candidate for the ancestral Pict, settled on the Gaulish-speaking Cotini (which he rendered as Gothuni), a tribe from the region that is now modern-day Slovakia. This was later misunderstood by Robert Sibbald in 1710, who equated Gothuni with the Germanic-speaking Goths. This was expanded on in 1789 by John Pinkerton, who claimed that Pictish was the predecessor to Modern Scots. Pinkerton's arguments were often rambling, bizarre and clearly motivated by his belief that Celts were an inferior people. The theory of a Germanic Pictish language is no longer considered credible.
Pre-Indo-European theory 
John Rhys, in 1892, proposed that Pictish was a non-Indo-European language. This opinion was based on the apparently unintelligible ogham inscriptions found in historically Pictish areas. A similar position was taken by Heinrich Zimmer, who argued that the Picts' supposedly exotic cultural practices (tattooing and matriliny) were equally non-Indo-European, and a Pre-Indo-European model was maintained by some well into the 20th century.
A modified version of this theory was advanced in an influential 1955 review of Pictish by Kenneth Jackson. Jackson proposed a two-language model: while Pictish was undoubtedly P-Celtic, it may have had a non-Celtic substratum and a second language may have been used for inscriptions. Jackson's hypothesis was framed in the then-current model that a Brythonic elite, identified as the Broch-builders, had migrated from the south of Britain into Pictish territory, dominating a pre-Celtic majority. He used this to reconcile the perceived translational difficulties of Ogham with the overwhelming evidence for a P-Celtic Pictish language. Jackson was content to write off Ogham inscriptions as inherently unintelligible.
Jackson's model became the orthodox position for the latter half of the 20th century. However, it has become progressively undermined by advances in understanding of late Iron Age archaeology, as well as by improved understanding of the enigmatic Ogham inscriptions, a number of which have since been interpreted as Celtic.

- All other research into Pictish has been described as a postscript to Buchanan's work. This view may be something of an oversimplification: Forsyth (1997) offers a short account of the debate; Cowan (2000) may be helpful for a broader view.

- See for example Bede HE I:1; Forsyth (2006) suggests this tradition originated from a misreading of Servius' fifth century AD commentary on Virgil's Aeneid.
Aeneid 4:146 reads: Cretesque Dryopesque fremunt pictique Agathyrsi.
Servius' commentary states: Pictique Agathyrsi populi sunt Scythiae, colentes Apollinem hyperboreum, cuius logia, id est responsa, feruntur. 'Picti' autem, non stigmata habentes, sicut gens in Britannia, sed pulchri, hoc est cyanea coma placentes. Which actually states that the Scythian Agathyrsi did not "bear marks" like the British, but had blue hair.
